To my hypothesis, there are a lot of crypto enthusiasts who are fond of keeping their private keys, Keystore / JSON File, seed words, mnemonic phrases etc to their wallet on cloud storage platforms like google drive and the several others. From my little research and experience, I personally think to keep these sensitive data isn't the best due to its nature of proneness to unauthorized accesses.
I'm positive there are individuals in this forum with profound knowledge regarding this topic. We would be grateful if you share with us your experience, tips, advice and most importantly, secured ways and means we can manage our private keys.
Thank You!
And then we have not to forget that to keep your private keys on google drive and other platforms it means you are trusting GOOGLE. What if one fine day Google should decide to steal your funds? Never say never.
